Abstract

Organic semiconductors provide the ability to directly manufacture thin 
film electronics including transistors, light emitting diodes, and solar 
cells. There has been recent interest in using organic materials as 
thermoelectrics for conversion of waste heat to electricity and also 
temperature control. We will discuss our efforts to develop methods to 
control the thermoelectric properties of semiconducting polymers. In 
this work, we have used emerging soft X-ray scattering methods and high 
resolution transmission electron microscopy to reveal structural order 
in semiconducting polymers to connect nanostructure with macroscopic 
properties. Using model systems, we have uncovered how the process of 
electrically doping semiconducting polymers influences their ultimate 
electrical properties. We will discuss the current state of performance 
of organic thermoelectrics and prospects for the future.

Bio

Professor Michael Chabinyc is Associate Chair of the Materials 
Department at the University of California Santa Barbara. He received 
his Ph.D. in chemistry from Stanford University and was an NIH 
postdoctoral fellow at Harvard University.He was a Member of Research 
Staff at (Xerox) PARC prior to joining UCSB in 2008. His research group 
studies fundamental properties of organic semiconducting materials and 
thin film inorganic semiconductors with a focus on materials useful for 
energy conversion. He has authored more than 150 papers across a range 
of topics and is inventor on more than 40 patents. He is currently an 
editor of /Journal of Materials Chemistry A/.
